should not worry. host: democrats line. laura. caller: i'm a 49-year-old african american. back in the day my parents used to give me this thing called father john. they made sure they gave us our vaccination, however i have learned that bad stuff builds up in -- that stuff buildup in the immune system. i also take cod liver oil. my daughter thinks that is the worst stuff, but she has never had the flu. i think sometimes we forget there were things we did not have in the past, and the things that people were taking to keep people alive, and just with the air we breathed now, it is dangerous. people could reflect on some of the things that old people take back in the day, like cod liver oil, which is still very cheap. you can build your immune system at an early age because he did not have to worry about the flu shot later on. i have a 16-year-old was never had the flu. maybe she had the sniffles when she was an infant. host: dr. friedman, do you want to start? guest: good nutrition is important, and vitamin d, which is in cod liver oil, could reduce your ability to be infected.
